Abstract

This research has been conducted to evaluate the allelepathic effect of herbal plant HEMP hydro alcoholic extract (Cannabis sativa L.) was conducted on seed GERMINATION and weeds growth of oat (Avena fatua L.), fat hen (Chenopodium album L.) and PIG WEED (Amaranthus retroflexus L.) in laboratory and greenhouse, using completely randomized design at three replications. The experiment treatments were extract of aerial organ of HEMP in 6 concentration 0.1, 0.25, 0.5, 1, 2.5 and 5% and distilled water (control). Different concentration of HEMP extract creates meaningful decreasing in GERMINATION percentage and radical and plumule lengths of weeds seeds in laboratory. Also the results showed different concentration of extract creates meaningful decreasing significantly in fresh and dry weight and height of plant in greenhouse.5% extract concentration causes decreasing shoot dry weight of Chenopodium album, Amaranthus retroflexus and Avena fatua until 0.73, 0.11 and 0.75 gr. Generally, increasing in HEMP extract concentration, decreased generation, dry weight and plant height of weeds in this study.
